of course we cannot compare the brand new thing with the old aa2. it does bring something good, especially ifak which you can be treatable after gunshots, and also much more detailed basic training with new point systems. besides one thing you cannot do in aa2 is to melee the enemy.
however they should bring some aa2’s features back. i don’t like the aim point which is much harder to hit the enemy and hard to see when background is in rich details. m320 is worse than m203 in both way of aiming & number of available rounds (that means my favourite, insurgent camp, cannot be converted). and you don’t know how many bullets left after firing few. it’s very hard to get good result for xm110 test even you aimed the target so well. i miss m24/m82 anyway.
